Why do all of our favorite styles go away???

I just removed the last, very last pair of Scojo popeyes reading glasses from the website. This single pair of +3.00 Black Ink popeye readers had been the last remaining symbol of a time that has passed. The time of small sleek aluminum cases with a flip top that protected sweet little rimless spectacles. The Popeyes reading glass was by far one of our most popular folding reading glasses for many years, and then, it was gone. Discontinued with no hope of revival.

Removing this item made me think of my other favorites that have gone away over the past 7 years of doing business and many came to mind. Lots of them were early generation Scojo styles like the Duane St or Varick, There was the Eyebobs Badboy, and most recently Slendereyes.

I guess the saying goes, all good things must come to pass, but dang it, if a style of reading glasses works for a whole slew of people, it has classic styling, and a good price point why does this have to be so?
